Stupid question, But i need to know. If my CPU runs at say 90-98% at times in a game, does that result in lower frame rate?
I suggest you do some testing. Install fraps to measure frame rates.
a) Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.
It is logical to me that as you improved your graphics capability, the cpu had to work harder to drive the new configuration to it's max.
Still, when any resourse gets above 70% or si, it indicates to me that that resource is becoming a limiting factor.
If your gaming experience is good, then don't worry about it.
If not, then look to see which improvement will be the more effective.
